This thread reminds me of a story, from "The Nudist on the Late Shift" by Po Bronson (a very funny book).
Bronson had tracked down one of the founders of Yahoo, who originally had no life and reputedly often slept under his desk -- but had become a billionaire in the dot-com run-up. Bronson's question was, well, when you become a billionaire how does your life change? -- "Do you still sleep under your desk?" was how he phrased it.
The guy's response was interesting: He had received so much mail as he became a wealthy celebrity that it was mounded up in his office. The mound was so huge that there was no longer room under the desk to sleep. So, yes, his life had changed in that respect.
(BTW, Bronson's "Bombardiers" is an even funnier book: a novel about nearly psychotic bond traders.)
